## Code Conventions

### Class Structure

- **Utility classes**: `abstract` class + `protected` constructor
- **Constants classes**: Same pattern

### Argument Validation

Use `AssertionUtil` at method entry:
- `AssertionUtil.assertArgumentNotNull("argName", value)`
- `AssertionUtil.assertArgumentNotEmpty("argName", value)`

### Exception Handling
